Sergey Shandar d23ba31dad Incorrect MSVC version detection ...

I know, Boost doesn't support MSVC 5.0 and 6.0. But the expression is invalid. Another way to fix it:
```c++
#   if _MSC_VER < 1300
      // Note: Versions up to 7.0 aren't supported.
#     define BOOST_COMPILER_VERSION 6.0
#   elif _MSC_VER < 1310
#     define BOOST_COMPILER_VERSION 7.0
```
